The location of nine chiral penta(ethylene oxide) side chains at the periphery of a C3-sym. H-bonded extended core gives rise to a thermotropic discotic liquid crystalline material that shows lyotropic phases in polar, protic media f (N,N’,N”-tris{3-[3′-(3,4,5-tris{(2S)-2-(2-{2-[2-(2-methoxyethoxy)ethoxy]ethoxy}ethoxy)propyloxy})benzoylamino]-2,2′-bipyridyl}benzene-1,3,5-tricarbonamide). The mol. stacks self-assemble in a reversible and hierarchical fashion, and specific and subtle solvent-mol. interactions together with the created hydrophobic microenvironment account for an unprecedented stabilization of a preferred handedness of the helical stacks by cooperative intermol. interactions. The presence of either chirality or achirality at the supramol. level in the stacks can be tuned by temperature and solvent as judged from CD spectroscopy. A hierarchical growth of the self-assembly is revealed using a variety of spectroscopic techniques and DSC. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Related Products of 75449-26-2
